Combination tool



Au 28, 1934. E. o. CLARK COMBINATION TOOL Filed Oct. 17, 1930 fdzzfarda67a 7'14 ATTORNEY Patented Aug. 28, 1934 UNITED STATES PATENT OFFICE 1Claim.

My present invention has reference to a combination tool for carpentersuse, and my object is the provision of a tool for this purpose thatcomprises a number of associated parts so that the same is capable ofattaining a number of functions which ordinarily require a separateinstrument or tool for obtaining desired results. The invention, and theadvantages thereof can be best understood from a perusal of thefollowing detailed description which is to be taken in connection withthe accompanying drawing and in which: 7

Figure 1 is a plan view of the improvement.

Figure 2 is a side elevation thereof.

Figure 3 is an end view thereof.

As disclosed by the drawing the improvement is small in size andcomprises parts which are foldable one over the other so that the toolprovides only a small package which may be readily stored in a workmanskit when not required for use. The tool may be constructed of anydesired material and includes a base 1 of a desired length. The base ishollow as at 2 for a distance from the bottom thereof and has its topprovided with a longitudinal depression or recess 3, the lower wallprovided by the depression being formed with an elongated slot oropening 4, the said opening extending through one end of the base asdoes the recess 3.

Arranged for sliding movement in the recess 3 there is a slide 5. Theslide 5 carries on its outer end a removable scribing element 6 and thepointed end of the said element is designed to be received in theopening 4, when the slide is moved fully into the recess 3 in thebase 1. The scribing element 6 is in the nature of an angle member andis attached to the slide 5 by removable means such as a bolt engaged bya nut, the pointed end of the scriber being projected beyond the underface of the slide.

The slide 5 has its end opposite that provided with the scribing element6 thickened, as at 7,

and the sides of this thickened portion have inscribed thereon scales 8as well as upper lines or marks 9.

The head 10 of the slide attaching bolt is ar-- ranged in the hollowbase 1 and the shank of the said bolt passes through the slot 4 andthrough an elongated slot 11 in the slide. The shank of the bolt isthreaded and is engaged by a knurled nut 12 which holds the slideadjusted on the base. The enlarged end 7 of the slide has embedded inthe top thereof a screw 13 which is engaged by a knurled nut 14, and thescrew passes through a longitudinal slot 15 in the upper element of theimprovement which is in the nature of a rule 16. On one of its ends theplate comprising the rule 16 has arranged on its outer face a block 17held on the rule scale through the medium of a pivot bolt 18 which isengaged by a knurled nut 19.

The rule 16 is provided with a round opening disposed on itslongitudinal center line and constituting an observation opening throughwhich the marks 9 on the enlargement 7 may be observed. The marks 9 aredisposed on opposite sides of the enlargement and if the rule be swungto one side or the other of the enlargement around the stud 13, one orthe other of the marks 9 will be exposed through the opening 20 and whenthe diagonal mark 21 on the face of rule is brought into registrationwith the selected mark 9, the rule will be disposed at an angle of 45with respect to the base 1 and may then be used to mark off miters.

The marks 21 are arranged in crossing relation with their points ofcrossing lying in the center of the hole or opening 20 and are inscribeddiagonally across the face of the rule at angles of 45 with the edgethereof.

When the rule is disposed transversely to the enlargement 7, so as to beat right angles with the base 1, it is not only secured in place by thenut 14 but is efiectively locked in position by the use of the block 17.But under this condition, the block 17 is removed from that end of therule to which it is shown in the drawing as connected and is applied tothe rule by having the stud 18 extended through the slot 15, when it maybe brought into abutting engagement with the face of the enlargement andits nut 19 tightened to hold it in such abutting position. The rule isthus effectively secured against being swung out of its right-angularposition, since it is then not maintained in such position merely by theclamping action of the nut 19.

Having described the invention, I claim:

A tool of the kind indicated comprising connected angularly relatedmembers, one of which is provided with an upstanding stud extendingthrough a longitudinal slot in the other, a clamping nut engaged withthe stud and bearing upon the slotted member for holding it at anyadjusted angular position relative to the stud carrying member, the studcarrying member being formed with flat faces on opposite vertical sides,and a detachable block having a stud insertable through the slot of theslotted member and a nut engageable with the stud to bear on the slottedmember to secure the detachable block thereto with a vertical face ofthe block in contact with a fiat face of the stud carrying member,whereby the slotted member and the stud carrying member may be fixedlysecured in right angular relationship.
